Two of the greatest marathon fields in history will contest the elite men’s and women’s races at the London Marathon when last year’s champions Daniel Wanjiru and Mary Keitany return to defend their titles.

In addition to Wanjiru (Kenya), the men’s race will feature the three greatest distance runners of their generation. Eliud Kipchoge (Kenya), Kenenisa Bekele (Ethiopia) and Mo Farah (Britain) have a combined total of eight Olympic gold medals and 12 World Championship golds between them.

Kenya’s Keitany will again go head-to-head with Ethiopia’s Tirunesh Dibaba, the 2017 runner-up in London who went on to win the Chicago Marathon in October.
